My customers are getting the wrong emails based on condition when they order for multiple items

I have a problem. When my customers place an order for multiple items, they are getting the wrong emails BUT all my conditions and emails are correct. Is there another reason this would happen? They get the right one when they only order 1 item but it seems to be confused when multiple items get selected. PLEASE HELP!!  I am still not able to use the mock cc you sent me to test this myself. I keep getting CARD ERROR.

I cannot seem to replicate this in the cloned version of your form. Here are the emails I get:

You are sending the email per item, I don't see any issues with this setup. This should work. Were you able to replicate the problem? 

As for the Test Cards, you need to set your Square integration into Test Mode. But I think this option has stopped working, it says FAILED when I click the button to connect to Square. I'm creating a ticket about it. I'll let you know here. 

Just to let you know that the Test Mode for the Square Integration is now fixed.  Please test it and let us know for issues.
